RAM 2500 Cummins 6.7L Diesel Engine Review **Heavy Duty Mechanic** | The BEST Towing Engine??

Great review

My dude is truck talkin in Jerusalem cruisers

I have a 2011 Ram 2500 6.7 cummins high output, 800lbs torque, and 3120,lbs of payload

Cummins the best ever. Great

6 in a row is the way to go

I had owned a 2010 Ram 2500 Cummins. Serviced by the book as i bought the maintenance contract. Biggest pile of crap. Leaked fluid and oil every other month. My driveway looked like a Jackson Pollak painting. Things fell apart, fender flares coming loose. Cabin lights flickered on and off. Then, on a trip across Nevada, the water pump seized. When it seized, it snapped the serpentine belt, and i was dead on Hwy 50. Had it towed back across from Austin to Fallon. Towed from Fallon to Reno to a Ram Dealership for repairs.

My back hurt like hell after several hours in the seat. Several times, the ignition would crank but wouldn't turn over. Then it would turn over and fire up. It was the top trim model and no power tow mirrors. 🤦‍♂️ just a pile or crap.

Bought a 2017 Ford 6.7. Not one problem for 41,000 miles. A few issues like sun roof track broke and the rear sensors went out. Got them fixed under extended warranty. Never failed to fire up and get me out and get me home. My back doesnt hurt after long hours behind the wheel. No problems with trim falling off or electrical gremlins. Now at a happy 114,000 miles. Much better vehicle. No matter how good the Cummins is, if the rest of the truck is junk, the entire truck is crap.

I actually hope they don't go to 10 speeds. The 10 speed allison in ford/chevy has clunky shifting and makes a constant high pitched whine.

Ill stick with my 2006 3/4 ton mega cab...no emissions, paid off, very simple and fun. The new trucks r super nice. Just dont wanna deal with emissions

Turn down the damn intro music. What’s wrong w/ ya

I Love Mine!

Need a video explaining the difference in a 2500 and 3500. And 3500 vs 4500 etc.

You should be locking the 68rfe out of 6th when towing that heavy

PLEASE PLEASE PLEASE do a towing test with the RAM 3500 with the HIGH OUTPUT! I’d love to see how it does. Thanks!

I am moving out of the V10 Gasser motorhome and into a 5th wheel, I am tired of 15MPH and 4 MPG on a moderate hill climb coupled with high Canadian fuel prices. A diesel makes more sense but they are insanely expensive and Ford and Chevy even more so, so I want to get this purchase right. The plan is a 15 K-ish trailer with a 2 K-ish payload, I am torn between 2021 3500 and 2500, this will not be a daily driver truck. I know a 2500 would have the capacity, but I am conflicted if I ever want to upgrade to a larger trailer I will be limited and won't be able to afford a bigger truck. Should I make the 3500 purchase now and have the capacity but a stiffer ride or go with a 2500. BTW, I am finding that the prices in Canada don't differ much between the 2500 and 3500. Great channel BTW!!!

I kept expecting the truck to break.

I'll stick with a mannie 5.9, thanks. Maybe less power, but I'll get where I want to go, every time.

Great vid, thx.

Another great video Alex! Yeah I like the Ram. I have a 2005 'Dodge' Ram in same color quad cab short bed with the 5.9 Cummins. Such a nice truck. We have had it since it was a pup and has 49k miles now. It is super reliable. We use it to pull our Airstream. I know you don't like the 68RFE transmission to much, I sure would love to have six speeds instead of just four. I have the 48RE in my Dodge. I tell you, wide RPM swings between gears, as I only have 4 and torque converter lockup. I have changed the transmission fluid regularly in mine and it hasn't given me any issues, (Knock on wood). Do you know if anyone swaps the 'Aisin' or even the '68' transmissions into the older 3rd gen Dodge Rams ? Is it doable? It would be cool to have a few more gears.
Have a good one and look forward to part two., Chuck,

I’m looking at Rams site now, the 6.7, 3.73, 4x4, crew cab, 6’4” bed is indeed 19,980lbs towing. Where are you getting only 17,200lbs?? I understand payload drops with each truck and more options bring down the payload number on the door sticker but I don’t see where the towing drops. For example the 6.4l Hemi online says 3340 payload while my door sticker says 3156 payload because I have more options. But again don’t see where the towing drops.

Мощный аппарат!

You do a great 👍🏻 job!!!!

I dig your videos but you started out throwing Ram under the bus when you said “with the infamous 6.7 Cummins”.

Infamous: having an extremely bad reputation: an infamous city. deserving of or causing an evil reputation; shamefully malign; detestable: an infamous deed.

Anyways again I felt like a correction is in order much like your did when explaining what transmission comes with the Ram 2500.

Thanks for another great video.

There’s really no comparison. Dodge has made no attempt to keep up with the Ford 6.7L. As someone who’s driven 45,000 miles up and down the east coast over the past year, I can honestly say the vast majority of trucks I see pulled over with the hoods popped are Rams. Ford has the diesel truck market cornered and steaming ahead.

I had a ford 6.7 overheat and shut down on the highway. Had it tow to mechanic they found a little bit of fuel in oil as well as little anti freez in oil pan. Motor still turns Although hard they Are telling me that the motor is junk . But they also hate the ford 6.7 to work on . Does this sound right or should i get a second opinion 😊

Powerstroke may have had to downshift, but it also has a 3.31 rear gear vs a 3.73 in the Ram. The 10 speed in the Ford has basically the same ~0.63:1 final overdrive, but 10 gear and 9th gears are actually really close together with 9th only being a 0.69:1 overdrive. Multiplying the 0.62*3.73 in the Ram gets you an OD ratio of 2.31:1 vs 10th gear in the ford gets you 2.08:1 and 9th about 2.28:1.

That'll get you pretty much the same RPM in the Ford in 9th at 110km/h (70mph) as in the Ram in 6th at the same speed. Now if i remember right the Ford did downshift further so his point still stands but just showing that going 10 to 9 isn't the jump in RPM you might think.

Fyi RPMs at ~110 km/h (exactly 70mph) for both trucks in their OD and direct drive gears (used same 33.2 inch tire for both as a 275/70R18 is basically standard on lower trims nowadays)

Ford:
7th:~2340rpm
8th:~1995rpm
9th:~1610rpm
10th:~1480rpm

Ram (6 speed so 2 OD gears only):
4th:~2640rpm
5th:~2150rpm
6th:~1650rpm

Both truck's peak torque is in that 1600-1700rpm range too.

As you can see the Ram in 6th is basically equal to the Ford in 9th. Goes to show while I do think the Ram still prbably does build low end torque a little easier, the Ford still has a ton of it too, and its 10th would put it 130rpm lower so harder to make Torque and Horspower. Although like I said early I'm pretty sure the Ford did have to drop to 8th at points but still.

None of this is to say I don't agree with the video. I do personally think the Cummins is the best with low end torque and likewise towing, and if you put the 10 speed with 3.31 gears behind the Cummins it'd probably maintain 10th easier than the Power stroke. Just trying to add some context as to why the Ford might've behaved a little differently.

I am actually really happy you chose this weight. It is heavy, and most people are not max towing. They might be towing with max payload, but that is a different set of issues. When you touched on how the truck took the hill without shifting that was super interesting. I do wonder if it would get slightly better MPG if it was down a gear? Do you recall if you were in tow mode?

What do you suggest a gas or a diesel truck when you’re going to be towing a 7,500LBD RV trailer a few times in the spring to fall season? Also being used as a daily driver?

Man you don't know what you're talking about-the 6.7 Cummins is just programming that restricts the power up at the higher RPM. Did you know that the marine version of the 6.7 Cummins is rated at 550hp at 3,300rpm?

Why did you call this 6.7 Infamous? In case you don't know Infamous means that it is bad, unpopular, bad, giving some bad quality. You should have called it just famous.

Sure wish you would do a more scientific evaluation IE use timers, etc. to get a more accurate idea of performance VS just a seat of the pants method of, “it feels faster or slower”.

I don’t know why they don’t go to a 10 speed, it seems like it would work especially well with all that low end torque.

Can’t compare to the the ford !! Or Chevy! Cummins are weak!

Cummins low RPM torque vs Powestroke and Duramax high RPM torque, why run when you can walk!

We have a 2016 2500 short bed with the 800 lb-foot 6.7. We particularly wanted the coil spring rear axle, which on this truck is a 6500lb gross rear axle weight.
We pull a 38’ Pinnacle fifth wheel that grosses at 15,000.
With a 3.43 rear end, I cruise at 63mph with the 68RFE locked in 5th.
Pulls the Rockies on I-70 without a problem.
60,000 miles without any problems. The combo turbo/ exhaust brake is great.
Just love my (wife’s) truck!

I'm in the market for my first ever diesel, i dont really need to tow but will need to go far distance a few weeks out of the year so I'm wondering if the ram 2500 or 3500 would be a better fit? Any thoughts or comments will be greatly appreciated

Not a race when towing.

Greetings Alex.
RAM 2500 with Cummins engine without HO; simply wonderful its performance and endurance.
Hard work is well bearable; but please don't forget its maintenance, because the ram knows how to kick your head, your wallet or both! 😮😢

Always a pleasure enjoy yours videos and comments Alex.

Thank's.

Love that motor. Would definitely have to go with the 3500 and the Asin. The 2500’s in the Ram has a HORRIBLE Tranny. Have has nothing but problems.

Another great video filled with helpful info :)

I have a 2005 dodge ram 2500 with air bags. I have a few mods that makes it a blast to drive.

This 2500 Ram Cummins with the rear air suspension you didn't mention! You did mention 68 RFE transmission! Junk not for heavy towing get the 3500 with the heavy duty Aisin transmission shifts designed for towing! Speed not key. Torque is key! Ram #1 in exhaust braking! #1 in comfort. Towing stay away from the Ram 2008-2023 Ram Cummins 2500 with the 68 RFE you will regret it! Don't buy it! The one you want Ram 1997-2007 Ram 2500 Cummins 2,3 gen models. These are Smog exempt models. The weak 🔗 48RE transmission.

A lot of the 68RFE problems are from jack asses doing big tunes or modifying the engine with big turbos or injectors.

If you keep your Cummins stock you’ll likely not have problems with it.

Cummins has its advantages in-terms of strength and simplicity. Easier engine to work on. When it comes time to replace the head gaskets on those aluminum duramax heads. You’ll know what I’m talking about.

This was only the low output cummins too, hopefully you get a chance to test the HO which is more comparable to the powerstroke.

Funny how comparing a 485lbft@3800rpm gas V8 to a 850lbft@1800rpm diesel I6 seem right? That 850lbft comes in at 1800rpm the Ford powerstroke peaks at 1600. The parts you are excluding here are the ratios involved. That powerstoke you tested had a 3.31 axle and ths ram is automatically has a 3.73. If you were to do the math at the wheels that Cummins has the mechanial advantageeven with less engine torque(top OD gears are similar). The comment about I6 RPM limitation, is spot on and 90% of people(including your tests) drive with RPM not the torque band. The Powerstroke 5 more torque than the cummins EVERYWHERE IN THE RPM BAND, except from 1750-1950rpm(SO Powerstroke) you should make a 3500 DRW test for the 4.10 ram and ford. You will see where the shine is and isn't. The issue with your testing method is you dont have control over what you get. That 3.5EB you tested was a 3.31 axle. You wont find a cometitor truck(GM or Ram) with over 10k tow rating with a high speed axles(let alone a 11700lb). GMs best with a 3.42 is 9200lbs, RAM 1500(5.7 V8 w 8spd) with 3.21 as 8440lbs. Rams 5.7 with a 3.92 with 10470lbs, still less than the Ford 3.5EB with a 3.31(11200 2wd, 11300lbs 4wd).

I like the comparisons, but I have no concern if truck A can make the run 2mins faster than truck B. I want to know which is the best bang for my dollar and what will last the longest without mechanical issues.

68RFE....... 🤣🤣🤣🤣

Really like this content, for someone like myself, who is in the market for a truck , this is gold.

love ur vids and wish I could buy merch from old north co but for some reason they don't ship to the u.s. but anyways always looking forward to ur vids!

That is not a 2023 ram 2500. It’s a 2022 or below
